All Night Long by Cynthia Cooke

At a wedding planner’s convention on a snowy mountain, Phoebe Lawson is one step closer to fulfilling her dream of being a wedding planner, until she literally drops into a snowdrift. Rescued by a Saint Bernard and the dog’s handsome owner, she thought her luck was turning, until Beau asks a favor. He needs a fiancé. The only vow Phoebe wants to keep is the one she’s made to herself—no men until her dream career is achieved.

Beau is running a bar in the small ski village but the owner who owns the building and adjoining hotel promised Beau’s late dad he wouldn’t sell Beau the bar/hotel until he gets married. Beau doesn’t believe in true love, nor does he believe in derailing his life to find a wife. Pushed against the wall and feeling out of options, Beau creates an engagement, and now he’s found the perfect fiancé.
A fake engagement, a Saint Bernard rescue on a snowy mountain, and suddenly this Valentine’s, Beau and Phoebe might discover the dream they really want is each other.
